Abstract
The invention provides a modified electric composite pipe. Rectangular threads are arranged on the outer surface of a polyolefin plastic pipe. When glass fiber reinforced plastic is wrapped, the inner surface of a glass fiber reinforced plastic pipe and the outer surface of the polyolefin plastic pipe are embedded in an interactive mode. A lathe device is additionally arranged between a polyolefin plastic pipe extruding device and a glass fiber reinforced plastic pipe production device. A roller rotates and the polyolefin plastic pipe moves forwards. The rectangular threads are turned on the outer surface of the polyolefin plastic pipe by a tool bit of a turning tool assembly. Glass fibers with liquid resin is wound around tooth spaces of the rectangular threads on the outer surface of the polyolefin plastic pipe, after the tooth spaces are filled and leveled up, glass fibers with liquid resin are wound around the tooth spaces in a reciprocating mode, and the tooth spaces of the rectangular threads can be filled with the glass fibers, so that the inner surface of the glass fiber reinforced plastic pipe and the outer surface of the polyolefin plastic pipe are completely embedded in the interactive mode, a gap is not reserved, the composite structure of the polyolefin plastic pipe and the glass fiber reinforced plastic pipe is reasonable, the polyolefin plastic pipe and the glass fiber reinforced plastic pipe cannot be stripped after being used for a long time, and the modified electric composite pipe is particularly suitable for ground-embedded electric pipes with the high requirement for ring stiffness.
Description
Technical field
The invention belongs to extraordinary power pipe production technical field, it is specifically related to a kind of modification electric power multiple tube and its production
Line equipment, production method.
Background technology
Extraordinary power pipe is mainly used as cable cover(ing), protects cable not to be subject to extraneous to damage it is ensured that Electrical Safety, electric power sheath
Pipe is mostly buried, and plastic pipe instead of original metal pipe material, and the major defect of existing electric power protecting pipe is
Ring stiffness not, is easily subject to ambient pressure deformation even fragmentation, brings potential safety hazard to power pipeline.For improving electric power plastic tube
Ring stiffness, people design outside and are coated with the electric power plastic tube of one layer of glass reinforced plastic pipe, generally have two kinds of versions.
A kind of version is to be bondd using viscose, produces plastic tube and glass reinforced plastic pipe respectively, in plastics tube outer surface
Smear adhesive, then glass reinforced plastic pipe is nested with outside plastic tube, make plastic tube be bonded in fiberglass after adhesive solidification
Inside pipe.This method is not easily controlled the amount smearing adhesive and uniformity, and adhesive is excessive or very few all can reduce plastics
Pipe and the adhesion of glass reinforced plastic pipe;Besides polyolefin plastic material, surface is more smooth, and the macromolecular chain of material composition presents
Nonpolar, it is inertia form, can solve the problem that the adhesion problem of fiberglass and polyolefin plasticss currently without adhesive.Experiment proves
Polyolefin plastic pipe and glass reinforced plastic pipe are unprocessed directly compound with adhesive, easily produce between the two after fiber glass resin solidification
Layer estranged comes off, and may produce inner lining plastic tube abjection it is impossible to draw electricity when meeting construction in plastic tube in transport process
Cable.
Another kind of version is setting glass cloth transition, will be wound around one layer of glass cloth, make after plastic tube outer surface hot melt
It is attached on the outer surface of plastic tube, and both adhesions are stronger, then is wound around and is soaked with the glass fibre of resin liquid and is fabricated to bag
After being covered with the electric power plastic tube of glass reinforced plastic pipe, glass cloth and glass reinforced plastic pipe also have stronger adhesion.This production method will be all
Even hot melting plastic tube outer surface just can make glass cloth be attached to strongly on plastics tube outer surface, plastic tube outer surface hot melt thickness
Glass cloth can be led to when inconsistent unbalanced with the adhesion of plastic tube and glass reinforced plastic pipe, or even lose the transition work of glass cloth
With, plastic tube and glass reinforced plastic pipe delamination;Besides production efficiency is more low, and labor intensity is larger, and production cost is higher.
The inapplicable production in enormous quantities of this method, is currently limited to small lot batch manufacture or experimental stage.
